Prokaryotic Cells: Smaller, single-loop chromosome.
Eukaryotic Cells: Larger, linear chromosomes.
1. Glycolysis
|
Cytoplasm
| - Glucose split into pyruvate - Small amount of ATP produced - Electron carriers accept e- and H+ to become NADH/FADH2 |
2. Preparatory reaction
|
Middle of Mitochondria
| - Pyruvate converted to acetyl-CoA and CO2 - Electron carriers accept e- and H+ to become NADH/FADH2 |
3. Citric acid cycle
|
Matrix of the Mitochondria
| - Acetyl-CoA completely broken down to CO2 - Small amount of ATP produced - Electron carriers accept e- and H+ to become NADH/FADH2 |
4. Electron transport chain
| Inner membrane of mitochondria | - The only step that requires O2 - H2O produced as a byproduct - Electron carriers NADH and FADH2 donate electrons and recycled back to NAD+ and FAD |
